What happened to my Griselinia hedge?? Can it be saved??

I bought a new home recently with 6 mature Griselinia (I believe) hedges at the back. Over the past month, I noticed the leaves turning black and brown with large spots of discolouration. Most of the leaves on every single hedge were affected. I completely cut the hedges back. I cut away all the leaves and the majority of the branches have been cut all the way back (see last pic).
The smaller, thinner branches and stems were soft and brown and it really did not look good. I’ve attached photos and I wanted some opinions on the hedge.

Will it likely grow back at all?

Is it completely dead?

If so, how would I go about removing it?

If it is not likely to recover, I’d like to plant some bare root 5-6ft cherry laurel hedges further ahead of the original Griselinia? Is this a good idea or not as I’d like to create some coverage fairly soon.

Thank you so much for any opinions/advice/help. I can’t stop thinking about this hedge and I’m so sad that it has succumbed to a disease or whatever has caused this.

    Hopefully someone will correct me if I'm wrong, but it sounds like the plants suffered some kind of disease such as Phytophthera. If that's the case I would remove them (including the roots) and leave the area fallow for a season, and replace with a resistant hedge plant. I'd avoid cherry laurel, I just think there are so many better hedging plants available.

    Also, although you want height quickly, younger plants often 'take' better and grow on more successfully, even though they start out smaller.

    I've no knowledge of Phytophthora but some RHS info here-

    It's possible it was caused by the summer heat and drought.
    There are a few trees in the area which will have very extensive root systems and will soak up any moisture available leaving little or nothing for anything else.
    If it is drought, they may recover. But they may not.

    Maybe it is Phytophthora or a similar fungus, but if it were me, I'd wait until Spring and see if there's any sign of life before doing anything too drastic.

    I agree .The weather this year has had a weird effect on so many different plants .If it were me I’d leave it till spring and see what happens before getting rid .
